it seems I can't install wireshark on my mac running Mavericks.
I have downloaded and linked it to Quartz. However, when I run the command /Applications/Wireshark.app/Contents/MacOs/Wireshark a pop-up comes up saying "Error loading MenuBar.nib".

Still not working...
The terminal tells me something like this:
Jul 15 11:30:53 localhost Wireshark[2427] <error>: The function `CGContextErase' is obsolete and will be removed in an upcoming update. Unfortunately, this application, or a library it uses, is using this obsolete function, and is thereby contributing to an overall degradation of system performance.
